The best way to protect yourself as a consumer is by knowing what to ask. The Frequently Asked Questions and Post-Cleaning Consumer Check List will give you a good understanding of the industry and the things to avoid when selecting an HVAC cleaning professional.  


Are there any health benefits that come from HVAC system cleaning?
Heating, ventilation, and air conditioning (HVAC) systems have been shown to act as a collection source for a variety of contaminants that have the potential to affect health, such as mold, fungi, bacteria, and very small particles of dust. The removal of such contaminants from the HVAC system and home should be considered as one component in an overall plan to improve indoor air quality.

Will HVAC system cleaning reduce our home energy bills?
Research by the U.S. EPA has demonstrated that HVAC system cleaning may allow systems to run more efficiently by removing debris from sensitive mechanical components. Clean, efficient systems are less likely to break down, have a longer life span, and generally operate more effectively than dirty systems.

What criteria should I use in selecting an HVAC system cleaner?
Interview as many local contractors as you can. Ask them to come to your home and perform a system inspection and give you a quotation. 

To narrow down your pool of potential contractors, use the following pre-qualifications:

• Make sure the company is a member in good standing of the National Air Duct Cleaners Association (NADCA). 
• Inquire whether the company is in good standing with your local Better Business Bureau. 
• Get proof that the company is properly licensed and adequately insured.
• Verify that the company is certified by NADCA to perform HVAC system cleaning. 
• Make sure that the company is going to clean and visually inspect all of the air ducts and related system components. 
• Avoid advertisements for "$99 whole house specials" and other sales gimmicks. 
• Ask if the company has the right equipment to effectively perform cleaning, and if the company has done work in homes similar to yours. Get references from neighbors if possible.
